His 3rd class medical and all the “certified” safety features in the world wouldn’t have prevented this, and it’s the reason the FAA will never achieve their goal of zero deaths: You can’t fix stupid. Meanwhile, it’s another “accident” statistic that makes GA look unsafe. When an idiot kills him/herself in a car, it’s recognized for what it is-stupid operation of an automobile. When it’s an airplane, somehow the FAA thinks they can fix it, or spend our last dollar trying!
